Cable coaxial CXT LSFH Dca 18RtC 250m white

The 250m CXT LSFH Dca 18RtC coaxial cable is a signal transmission solution designed for environments that require high reliability and fire safety. Manufactured with double shielding technology, this product guarantees the integrity of the signal in fixed and permanent installations, being ideal for television networks, professional audio and video surveillance systems in public or industrial buildings where the regulation of reaction to fire is strict.

Technical characteristics

• Internal driver: Rigid copper of 1 thread (Class 1) with diameter of 1 mm and uncovered surface.
• External drivers: Copper-plated aluminium mesh (Cu/CCA) type foil + braided.
• Dielectric: Expanded polyethylene foam (PE) to optimize transmission.
• Armoring: Double screen layer for maximum electromagnetic protection.
• Characteristic impedance: 75 Ohm.
• Approximate outer diameter: 6.6 mm.
• Cover: White LSFH material.
• Operating temperature: -25...70 °C in both flexible and fixed mode.
• Minimum radius of bending (fixed): 33 mm.
• Fire reaction class EN 13501-6: Dca (smoking behaviour s2, drops/particles d2, acidity a2).

Due to its double shielding and foam dielectric, this cable minimizes signal attenuation and protects against external interference, ensuring a stable connection over long distances. Its LSFH cover complies with strict European regulations, making it suitable for installations in high-risk areas where the spread of fire must be contained.

For installation, the cable must be fixed every 1 meter using specific supports to avoid mechanical stresses.
